- Аннотация: Green synthesis of carbon quantum dots (CQDs) from natural sources always remain an attraction due to their excellent optical properties. In present work, highly fluorescent N, S co-doped CQDs (NS-CQDs) were synthesized from banana (musa acuminata) juice using a simple one-step hydrothermal process, which not required any surface passivation, oxidizing agent or inorganic salt. Transmission electron microscopic images and X-ray diffraction analysis revealed spherical shaped NS-CQDs of an average size of 1.27 nm with poor crystallinity. The proposed method offers higher quantum yield (32 %) at an excitation wavelength of 330 nm as compared to other reported natural sources-derived CQD. These synthesized NS-CQDs utilized as a fluorescent probe for the detection of Cu (II) in the water sample. The fabricated fluorescent sensor displayed the detection of copper ions in the concentration range of 1−800 μg/mL with the LOD of 0.3 μg mL−1.
